UNCLASSIFIED 7 TLP:WHITE 1 IDENTIFICATION OF TARGET OF EVALUATION The Target of Evaluation (TOE) is identified as follows: Table 1: TOE Identification TOE Name and Version Samsung 5G gNB AU, DU v19.A Developer Samsung Electronics Co. Ltd. 1.1 COMMON CRITERIA CONFORMANCE The evaluation was conducted using the Common Methodology for Information Technology Security Evaluation, Version 3.1 Revision 5, for conformance to the Common Criteria for Information Technology Security Evaluation, Version 3.1 Revision 5. The TOE claims the following conformance: collaborative Protection Profile for Network Devices, v2.2e, 27 MAR 2020 1.2 TOE DESCRIPTION The TOE is a network device performing an infrastructure role at the edge of next generation 5G cellular networks. The TOE, which may be either a DU device, or an AU device, is deployed within a gNB system at the edge of 5G cellular networks. The AU incorporates a Radio Unit (RU), whilst the DU requires a separate RU. 1.3 TOE ARCHITECTURE A diagram of the TOE architecture is as follows: TOE Architecture UNCLASSIFIED 8 TLP:WHITE 2 SECURITY POLICY The TOE implements and enforces policies pertaining to the following security functionality:  Protected Communications  Secure Administration  Trusted Update  System Monitoring  Self-Test  Cryptographic Operations Complete details of the security functional requirements (SFRs) can be found in the Security Target (ST) referenced in section 8.2. 2.1 CRYPTOGRAPHIC FUNCTIONALITY The following cryptographic implementation has been evaluated by the CAVP and is used by the TOE: Table 2: Cryptographic Implementation Cryptographic Module/Algorithm Certificate Number Samsung 5G gNB AU, DU v19A C1875 UNCLASSIFIED 9 TLP:WHITE 3 ASSUMPTIONS AND CLARIFICATION OF SCOPE Consumers of the TOE should consider assumptions about usage and environmental settings as requirements for the product’s installation and its operating environment. This will ensure the proper and secure operation of the TOE. 3.1 USAGE AND ENVIRONMENTAL ASSUMPTIONS The following assumptions are made regarding the use and deployment of the TOE:  The Network Device is assumed to be physically protected in its operational environment and not subject to physical attacks that compromise the security or interfere with the device’s physical interconnections and correct operation. This protection is assumed to be sufficient to protect the device and the data it contains. As a result, the cPP does not include any requirements on physical tamper protection or other physical attack mitigations. The cPP does not expect the product to defend against physical access to the device that allows unauthorized entities to extract data, bypass other controls, or otherwise manipulate the device.  The device is assumed to provide networking functionality as its core function and not provide functionality/services that could be deemed as general-purpose computing. For example, the device should not provide a computing platform for general purpose applications (unrelated to networking functionality).  A standard/generic Network Device does not provide any assurance regarding the protection of traffic that traverses it. The intent is for the Network Device to protect data that originates on or is destined to the device itself, to include administrative data and audit data. Traffic that is traversing the Network Device, destined for another network entity, is not covered by the NDcPP.  The Security Administrator(s) for the Network Device are assumed to be trusted and to act in the best interest of security for the organization. This includes appropriately trained, following policy, and adhering to guidance documentation. Administrators are trusted to ensure passwords/credentials have sufficient strength and entropy and to lack malicious intent when administering the device. The Network Device is not expected to be capable of defending against a malicious Administrator that actively works to bypass or compromise the security of the device.  The Network Device firmware and software is assumed to be updated by an Administrator on a regular basis in response to the release of product updates due to known vulnerabilities.  The Administrator’s credentials (private key) used to access the Network Device are protected by the platform on which they reside.  The Administrator must ensure that there is no unauthorized access possible for sensitive residual information (e.g. cryptographic keys, keying material, PINs, passwords etc.) on networking equipment when the equipment is discarded or removed from its operational environment. UNCLASSIFIED 10 TLP:WHITE 3.2 CLARIFICATION OF SCOPE The TOE incorporates CAVP-validated cryptography and was not subjected to CMVP (FIPS-140) validation. Only the functionality covered in the collaborative Protection Profile for Network Devices, v2.2e is included within the scope of the evaluation, the 5G related functions were not evaluated.

Documentation and process dealing with Development, Guidance Documents, and Life-Cycle Support were evaluated. 5.1 DEVELOPMENT The evaluators analyzed the documentation provided by the vendor; they determined that the design completely and accurately describes the TOE security functionality (TSF) interfaces and how the TSF implements the security functional requirements. The evaluators determined that the initialization process is secure, that the security functions are protected against tamper and bypass, and that security domains are maintained. 5.2 GUIDANCE DOCUMENTS The evaluators examined the TOE preparative user guidance and operational user guidance and determined that it sufficiently and unambiguously describes how to securely transform the TOE into its evaluated configuration and how to use and administer the product. The evaluators examined and tested the preparative and operational guidance and determined that they are complete and sufficiently detailed to result in a secure configuration. Section 4.1 provides details on the guidance documents. 5.3 LIFE-CYCLE SUPPORT An analysis of the TOE configuration management system and associated documentation was performed. The evaluators found that the TOE configuration items were clearly marked. The evaluators examined the delivery documentation and determined that it described all the procedures required to maintain the integrity of the TOE during distribution to the consumer. UNCLASSIFIED 13 TLP:WHITE 6 TESTING ACTIVITIES Testing consists of the following three steps: assessing developer tests, performing independent functional tests, and performing penetration tests. 6.1 ASSESSMENT OF DEVELOPER TESTS The evaluators verified that the developer has met their testing responsibilities by examining their test evidence, and reviewing their test results, as documented in the Evaluation Test Report (ETR). The correspondence between the tests identified in the developer’s test documentation and the functional specification was complete. 6.2 CONDUCT OF TESTING The TOE was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The detailed testing activities, including configurations, procedures, test cases, expected results and observed results are documented in a separate Test Results document. 6.3 INDEPENDENT FUNCTIONAL TESTING During this evaluation, the evaluator developed independent functional tests by examining design and guidance documentation. All testing was planned and documented to a sufficient level of detail to allow repeatability of the testing procedures and results. The following testing activities were performed: a. PP Assurance Activities: The evaluator performed the assurance activities listed in the claimed PP b. Cryptographic Implementation Verification: The evaluator verified that the cryptographic implementation claimed is present in the TOE. 6.3.1 FUNCTIONAL TEST RESULTS The developer’s tests and the independent functional tests yielded the expected results, providing assurance that the TOE behaves as specified in its ST and functional specification. UNCLASSIFIED 14 TLP:WHITE 6.4 INDEPENDENT PENETRATION TESTING The penetration testing effort focused on 4 flaw hypotheses.  Public Vulnerability based (Type 1)  Technical community sources (Type 2)  Evaluation team generated (Type 3)  Tool Generated (Type 4) The evaluators conducted an independent review of all evaluation evidence, public domain vulnerability databases and technical community sources (Type 1 & 2). Additionally, the evaluators used automated vulnerability scanning tools to discover potential network, platform, and application layer vulnerabilities (Type 4).
